DEK shows next-generation solar metallization solutions at Shanghai

DEK is showing its next generation solar metallization line solutions at the SNEC PV Power Expo 2009 event in Pudong, Shanghai from the 6th to 8th May. The screen printing specialist is previewing details of its latest high-throughput PV3000 silicon cell metallization concept and running its state-of-the-art PV1200 metallization line live in Hall 6, Booth T621.


Visitors to the DEK booth at the SNEC event will be able to watch a video of the PV3000, the company’s latest innovation in crystalline silicon solar cell metallization that boosts throughput and productivity by using multiple print heads concurrently. In addition, the print heads themselves will be on display.

The PV3000 promises consistently high rates of productivity to suit the escalating global demand for solar cells by combining DEK’s expertise in exceptional print platform accuracy and repeatability with industry-leading process knowledge. To minimise breakage and waste, the new PV3000 system also features the same meticulous mechanical handling attributes as demonstrated at previous trade events on DEK’s PV1200 line, which uses real 150 micron silicon wafers cycling continuously during the shows.

The PV1200 will also be on display at SNEC, again cycling real c-Si wafers during live demonstrations on the booth. The PVP1200 screen printing platform is built using the precision expertise that has driven the DEK’s established screen printing platforms proven in surface mount assembly and semiconductor packaging to achieve six-sigma process capability at a resolution of ±12.5 micron for maximum repeatability and advanced levels of accuracy. The platform also benefits from DEK’s precision emulsion screen expertise, manufactured in-house under class 10,000 cleanroom conditions.

Special features include dedicated handling for thin wafers, ensuring low breakage rates for maximum yield, in addition to high-speed machine vision capabilities ensuring perfect alignment from the first wafer. On display from Booth T621 in Hall 6, the PVP1200 will be featured alongside the PV1200 Coinstack Unloader and Re-Loader, demonstrating how DEK’s solar cell process expertise substantially extends the viability of commercial solar cell manufacture.

“We look forward to previewing aspects of our new PV3000 system to manufacturers and to showing how the PV1200 line offers PV cell producers a valuable turnkey solution, which we are able to deliver and install within a short timeframe,” explains Darren Brown, Alternative Energies Business Manager for DEK. “Showcasing select solar technologies live on our metallization line, visitors to the SNEC show will see how easily new entrants to the solar cell market will benefit from our expertise by being able to get productive quickly with minimal training. Companies already active in this sector will appreciate enhanced support, low cost of ownership and short delivery times for the PV1200 line and are bound to be interested in the very high throughputs rates we can promise with the PV3000.”
